Exam 14: A: Central Nervous System

The islands of gray matter inside the hemispheres of the cerebrum are known as the cerebral cortex.

Association tracts connect parts of the same cerebral hemisphere.

The lateral ventricles are located within the cerebellum.

The structure in the brain called the olive is found in the midbrain of the brainstem.

Based on the system of naming tracts in the spinal cord,the corticospinal tract would be a descending tract.

The vermis lies between the two hemispheres of the cerebellum.

The shallow grooves of the cerebrum are called gyri.

To describe sensory pathways as "crossed" refers to the fact that each side of the brain registers sensations from the opposite side of the body.

The corpus callosum is an example of a commissural tract of the cerebrum.

A primary function of the reticular formation is to arouse or alert the cerebral cortex.

Both the inferior colliculi and superior colliculi are found in the midbrain.

The hypothalamus is the only part of the brain able to release a hormone.

The pia mater has three important inward extensions: the falx cerebri,the falx cerebelli,and the tentorium cerebelli.

The tracts that make up the middle cerebellar peduncle come from the pons.

The location of the crossing of the left and right optic nerves is called the epithalamus.

There are about 23 ml of cerebrospinal fluid in the nervous system.

Projection tracts pass through the corpus callosum from one hemisphere of the cerebrum to the other.

The tentorium cerebelli separates the cerebellum from the cerebrum.

The hypothalamus plays a role in regulating water balance in the body.

The ependymal cells are glia cells that assist in the production of cerebrospinal fluid.
